Hello, i happen to own a 1991 Chevy 350 ss Truck. It has the 5.7 litter v8 with the Tbi. They are good motors not huge power houses but are relitivly good on gas. What I am currently working on is installing 1996 cast iron vortec heads, camming it out and throwing a carb 650 demon on it. This will really open it up. But over all the stock motor has a decent amount of power. Mine has 230 hp and about 260-275 Ftq. Anyways you can check it out on Youtube. Just type in Chevy 350 ss.
